To (tZl whom it may concern.-

Be it known that l, \VILLLUE F. BL'ckLnv, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Dynamo-Electric Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, referencebeing had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure 1 of the drawings is a representation of a longitudinal vertical sectional view of my invention. Fig. 2 is a transverse vertical sectional view of the same. Fig. 3 is a view of one of the comnmtator-heads Fig. l is aview of the rockers for holding the brush-holders. Fig. 5 is a view of one of the brush-holders. Fig. 6 is a sectional view of a part of the standard for supporting the commutatorbrushes. Fig. 7 is an end view of the armature, showing the coil-wires. Fig. 8 is a top view of one of the armaturesections. Fig. 5) is a view of one of the armaturesections with bobbins removed, and Fig. 10 is a view showing the ends of the cylimler-magnets and the armaturc-hub in section.

This invention has relation to dynamoelectric machines for electric light-ing, electroplating, Eve; and it consists in the construction and novel arrangement of devices, as will be hereinafter fully described, and particularly pointed out in the claims, appended.

Referring by letter to the accompanying drawings, A designates the armature, and H the hub. 13 are the bolts that secure the magnets M M M M to the standards or frames S S.

l? I designate the pole-pieces nearly surrounding the armature.

L are the bolts by which the pole-pieces are secured to the cores of the magnets 3f, all of the magnets being wound with wire, as usual, \V designating the wire.

B designates an iron base, to which. the standards are secured by bolts G (t.

S designates the shaft, having bearings in boxes on the standards S S, and carrying the driving-pulley P at one end.aud the armature A intermediately of the drivingpulley and the commutator E. The pole-pieces F P eX- tend down over the ends of the armature, and nearly encircle the armature, thus giving a strong magnetic field.

T indicates a hard-rubber tube, with two iron or brass heads, T V, secured to it by screws a: .t

U are the brass segments of the commutator, and are of the usual construction. D l) are the brush-holders, and l.) D the brushes, made of brass.

G designates the rocker to which the brushholders are secured, and insulated therefrom by hard rubber, as shown. The rocker G is movably affixed to the standard J", through which the shaft S freely revolves. A screw, a,'holds the rocker in position on the stand ard S. The brushes are bound in the brushholder by screws K K. The commutatorheads are provided with holes X X, through which the wires from the spools on the armature pass to corresponding segments of the connnutator. These holes X N serve to keep the commutator cool by permitting a circula tion of air through them.

13" 13 designate the bolts that secure the armature-sections A to the hub II.

In Fig. 8 a top view of one ofthe armature sections shows the cores l" (i over which wire is wound, and shows also how the cores are removably secured to the sections by screws.

designates a groove through which the connectingwire is passed between the spools or bobbins B.

In Fig. 9 an armaturesectionis shown with the bobbins removed for repairs or rewinding. The armature-sections are all of iron, and cast in the shape shown in Fig. .l, with a slot planed across their under sides, to permit them to be fitted closely to the hub and secured in place by bolts, as shown. The cores of the bobbins are made to slide into the armature-sections. and are secured in place by screws. Spaces F are left between the sections,to permit a circulation of air for the dispersion of heat, and to cut off the Foucault currents to some extent. The manner shown of securing the sections to the hub admits of a great number being em ployed, thereby increasing the power of the IOO machine. The coils of the bobbins on the armature are all wound in the same direction, and the bottom end or inside end of one coil is connected to the top or outside end of the other coil on the same armature-section, and the bottom or inside end of that coil (the one last mentioned) is connected to the bottom or inside end of the diametrically-opposite coil, so that the bobbins are connected in series, and the last two ends of the coils are soldered to the brass collars or commutators, which are insulated from the shaft S by hard rubber, as shown. The circuit of the armature is put into the field-circuit in the usual and wellknown manner.

The manner of connecting the armature sections A to the hub is clearly shown in Fi 10, the bottom of the neck portion 0 of tne section being planed away, so that it will sit astride of the hub when in place. The bobbins, when in place, occupy the spaces 0" at the sides of the neck portion 0.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An armature composed of the armaturesections, having the neck portion 0' and spaces 0 0 at its sides, to receive the bobbins, which are removably secured therein by screws, the

neck portion of each armature-section being planed away in its lower side to fit astride of the hub H, and secured thereto by bolts 13*, spaces being left between the sections, and grooves g provided in their faces, for the bobbin-connecting wires,substantially as specified.

2. An armature section having the neck portion 0, the spaces 0, and the removable bobbinsB, secured in place by screws,substantially as specified.

3. A commutator for dynamoelectrie machines, having two brass or iron heads, V V, secured to the hard-rubber tube T by screws, and provided with holes N, for the passage of the wires from the armature to the commutator-segments, substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.
